M193 80

[ei276b]

I just picked up some 1X fired brass at the range from some guys shooting next to me stamped M193 and the other side 80 which I presume is the year. No other markings. They were shooting AR-15's. I believe it is 5.56mm but it does not say .5.56 or .223 on the case head. I have never loaded anything with this head stamp. Is it Nato spec? It's probably common knowledge but I have been shooting 30 cal. for many years. If one of you knowledgeable guy's would clue me in I would be thankfull. Thanks in advance.

M193 is the 55 grain bullet load used by the military. If it is NATO spec ammo it will also have a circle with a cross on the headstamp.
Since this does not, it was probably some contract ammo that did not meet military specs. Not to worry, the brass should be reloadable.

It is boxer primed. Yeah, no circle with a cross. No crimp either. Thanks.

If the headstamp is M193 it sounds like the stuff from Centurion. Reloadable, but it is not M193 spec. Also, I am guessing the "80" is "08".

M-193 is not NATO stamped. M-855 (AKA SS-109) is NATO marked.
